Kanye West -- Brutal Shoe Attack in New Song ... Nike Sucks!!!

Kanye West dropped a new song on New Year's Eve, in which he declared nuclear war on Nike.

The Yeezy's creator skewered his competitor, claiming Nike treats people like slaves and opened the vault to keep Lebron from bailing. He goes on to say Drake's all Nike's got now.

And Kanye's got some choice words for Bill Cosby ... "Do anybody feel bad for Bill Cosby, did he forget the names just like Steve Harvey?"

And Kim Kardashian's hubby bragged about his wife's latest venture, boasting they made a million bucks a minute off the kimojis.
